Similar parts are designated by the same reference characters in theseveral figures.

The preferred embodiment of the invention is shown in the accompanyingdrawings and will be hereinafter described in detail, but it is to beunderstood that the invention is not restricted to the preciseconstruction shown since equivalent constructions are contemplated andsuch will be included within the scope of the claims.

In the accompanying drawings, the mold disk l, as shown in Fig. 1, is ofconventional construction, it being mounted for rotation on a shaft 2carried on a reciprocable slide mounted in suitable guides in themachine and having a bearing arm 3 projecting from a side thereof, theconstruction and operation of the same as in commercially used machinesof the class referred to and forming no direct part of the presentinvention so that further illustration and description thereof is deemedunnecessary. Machines of this class as commercially used also employ aso-called first elevator or line transporter, the lower portion of whichis designated 4 in Fig. 1, this first elevator operating in the usualand well known manner to receive assembled lines of matrices, to thenlower the matrix lines into casting position in front of the mold on themold disk and to subsequently elevate'the matrix line by upward movementof this elevator or transporter to a level where the matrix line isremoved therefrom for distribution of the matrices. Since theconstruction and operation of the first elevator or transporter 4 arethe same as in machines of this class as commercially used and suchelevator or transporter forms no direct part of the present inventionother than that its usual upward and downward movements afford means forcontrolling or motive power for moving the banking members according tothe present invention, as will be hereinafter described, furtherillustration and description of such elevator or transporter is deemedunnecessary.

Machines of this class also employ a so-called knife block for trimmingthe sides of the slugs as the latter are ejected from the mold, one formof such a knife block being designated 5, it carrying the usual righthand and left hand slug trimming knives 6 and 1 respectively, the blockbeing mounted on the usual vise frame 8 in which the elevator 4 isguided to move vertically, and the knife 6 is adjustable toward and.from the knife 1 by means of an annular rim 9 which is connected to ascrew H! which is threaded in the knife block 5, rotation of this screwby the rim 9 setting the knives at difierent distances apart accordingto the thickness of the slug to be trimmed when the latter is pushededg'ewise bethis slide being tween the knives during its ejection fromthe mold. Detailed disclosure of the construction and mode of operationof the knife block shown is set forth in U. S. Letters Patent No.1,202,720 granted October 24, 1916, but it is to be understood thatknife blocks of other forms may be used in carrying out the presentinvention.

The right hand and left hand vise jaws II and I 2 are mounted to slidetoward and from one another in the upper portion of the vise frame, asusual in machines of this class, but these vise jaws in the presentinstance are provided with ribs l3 which project from the rear facesthereof which normally stand opposite to the mold, these ribs extendingthroughout the lengths of the respective jaws, and. these ribs areintended to cooperate with the mold in use while it is in castingposition by entering a recess I4 which extends across the front facethereof, when the mold disk makes its first advance toward the vise jawsand the matrix line which, it will be understood, is clamped endwisebetween the opposed faces l and I S of the respective jaws, such advanceof the mold disk taking place preparatory to the slug casting operation.Several molds maybe mounted in annularly spaced relation on the face ofthe mold disk, it being usual in practice to employ molds having castingslots which vary in size so that the machine may be set to cast slugs ofdifferent point size or thickness merely by selecting one or another ofthe molds. For example, the mold disk according to Fig. 1 is providedwith four molds one of which molds however, does not appear since suchmold and the adjacent portion of the mold disk is broken away to moreclearly show the knife block and the banking elements associatedtherewith. Since Fig. 1 shows the mold disk as viewed from the rear,only the rear faces of the molds and the outlines of the casting slotstherein are visible. It will be seen from this figure however, that themold designated generally by the numeral ll stands in a horizontalposition at the top of the mold disk, which is its casting position, itbeing understood that this mold, after the casting operation has takenplace, will be brought, by rotation of the mold disk in the direction ofthe arrow in Fig. 1 through 270 degrees, into a vertical position at theleft hand side of this figure and between the ejecting device and theknife block. Usually, and as shown, the casting slot IS in the mold I!is appreciably wider or higher than the casting slot 26 in the mold I8,and the casting slot 22 in the mold 2| is wider or higher than thecasting slot in either of the molds I8 and I9.

Assuming that the ribs l3 on the vise jaws are of such vetrical heightas to enter or fit into the recess M in the front of the mold l1, itwill be evident that the mold ll can advance in the usual manner tobringits front face against the opposed faces of the vise jaws so that theseparts come together in metal-tight engagement, as shown in Fig. 6, thisbeing the relation of the parts during the casting operation. However,the three-quarter revolution of the mold disk, subsequent to the castingof a slug in the mold I! carries this mold to a vertical positionopposite to the trimming knives, and the mold l8 will then occupy thehorizontal or casting position at the top of the mold disk, and upon thesecond advance of the mold disk to bring the mold I1 into closeproximity to the trimming knives prior to the ejection of the slug, therelatively narrow recess M along the front of the casing slot 20 A lug52 fixed on in the mold l8 will not be suitable for entrance therein ofthe rib l3 on the vise jaws. Consequently, the second advance of themold disk for the ejection of the slug from the mold in use wouldordinarily be obstructed by engagement of the ribs on the vise jawsagainst the front of the mold which is then in casting position.

In machines of this class, the mold disk under ordinary conditions isarranged to advance the mold in use the same distance while it is incasting position as it does when such mold is in the ejecting position,and a banking surface or surfaces are usually provided at suitablelocations on the knife block to be engaged by one or another portion ofthe front of the mold to support the latter against the forward thrustof the ejecting device, the usual ejecting blade E50 engageabie with therear edge of the slug S being shown in the present instance. Accordingto the present invention, banking surfaces are provided to support themold during the slug ejecting operation which surfaces shorten or limitthe extent of the second advance of the mold disk in order to avoid theaforementioned faulty condition due to the ribs on the vise jaws foulingagainst the front face of a mold in casting posi tion which is notsuited to accommodate such ribs when another mold which has beenselected for use is standing in the ejecting position. However, toenable the mold disk to make its full advance against the mold in useand in casting position during the casting operation, the presentinvention provides means for moving these banking surfaces out of activeor limiting position during the casting operation and for moving thesebanking surfaces into active position to limit the advance of the molddisk only during the ejecting operation.

The means provided by the present invention for accomplishing thehereinbefore stated objects, as shown in the present instance, comprisesa rock shaft 23 which is rotatably mounted in a bore 24 forming abearing in the vise frame, this shaft having an arm 25 fixed to one endthereof and an arm 25 fixed to its other end. A vertical rod 21 isloosely connected to the outer end of the arm 26, as by a pin 28, therod 21 being slidable in a slot 29 in the forward side of a plate 39secured by screws (H to the knife block. or forming a part of the rodlaterally therefrom is engagein a banking block 3 3, the latter beingslidably guided for vertical movement in a slot 35 in the plate 39 andbearing on its forward side against an upwardly and rearwardly inclinedsurface 35 on a portion of the right hand knife opposite to the slot 35.

The outer end of the arm 25 is loosely connected, as by a pin 3'1, to avertically reciprocable bar 38, the upper end of which is connected to avertically disposed rod 39 having upper and lower banking blocks 45 andM thereon. These banking blocks are mounted to slide vertically ingrooves 42 in the knife '5, they being held in 2! and projecting able ina notch 33 these grooves by upper and lower retaining plates 63 and 44respectively, the forward sides 65 of the blocks M! and 4! being slopedto conform with the upwardly and rearwardly inclined surfaces 45 onportions of the knife l at each side of the grooves 42. v

The banking blocks 34, so and M are controlled or set into active andinactive positions automatically and at the proper times during theoperation of the machine. In the present instance, the usual firstelevator or line transporter of the machine is utilized to effect suchcontrol or movements of these banking blocks, for which purpose thelower end of the bar 38 is provided with a vertically elongated slot Mto accommodate a stud 48 carried by a vertically reciprocable rod 49which constitutes the main operating rod for the well known knife wiperbar 58 and wiper blade 5i which are mounted on the vise frame and areemployed on commercial machines of this class for scraping chips removedfrom the slugs from the cutting edges of the trimming knives. The knifewiper is usually arranged to slide vertically up and down over thecutting edges of the knives under the influence of the verticalmovements of the usual first elevator or line transporter 4, the latterhaving an arm 52 fixed thereto at its lower end and provided with a bore53 through which the rod 49 is slidable, a spring 54 bearing at itsupper end on a fixed collar 55 on the rod 59 and at its lower endagainst the arm 52 serving to yieldingly force the wiper blade 5iupwardly when the line transporter makes its upward stroke to carry thematrix line from casting position to distributing position. When theline transporter returns from its upper or line distributing position toits normal line receiving position, the operating rod 49, together withthe bar 55 and wiper blade 5|, descend by gravity to return the wiper toits normal position shown in Fig. l.

The operation of the mechanism hereinbefore described, is as follows:

Assuming that a slug has been cast in the mold H which occupies theusual horizontal casting position at the'top of the mold disk, as shownin Fig. 1, the line transporter l which, at this time stands in itslowermost position to present the matrix line therein in front of themold, ascends, subsequent to the cast, to an upper level for removal ofthe matrix line therefrom and distribution of the matrices. Prior tosuch ascent of the transporter, the mold disk, as usual, retreatsrearwardly from the matrix line, and during the ascent of the linetransporter from casting position, the mold disk is rotated 270 degreesby the usual driving pinion (not shown) in the direction of the arrow,Fig. l, to bring the mold ll to a vertical position opposite to theknife block, such rotation of the mold disk being stopped when thecasting slot H3 in this mold stands in alinement with the slug passageor opening between the trimming knives 5 and l. Rotation of the molddisk to bring the mold ill to such position for ejection therefrom ofthe slug cast therein and the pushing of such slug forwardly between thetrimming knives, results in locating the mold ill in the horizontalcasting position previously occupied by the mold H, but since the recessl i in the face of the mold is is too narrow to accommodate therelatively wide ribs 83 on the vise jaws, the usual second advance ofthe mold disk, immediately preceding the ejecting operation, must belimited to such an extent as will avoid obstruction to such advance ofthe mold disk by engagement of the face of the mold ill with the ribsl3. Means for limiting the advance of the mold disk while the mold inuse is in ejecting position is set during the ascent of the elevator ortransporter 3 and while the mold disk is turning the mold in use to theejecting position, such ascent of the elevator or transporter moving thebanking surfaces on the banking blocks 3 ii and M upwardly by engagementof the stud as against the upper end of the slot ll in the reciprocablebar 38, such engagement taking place toward the end of the ascendingmovement of the transporter and rocking the shaft 23 sufiiciently tolift the bars 2? and 39 and thereby slide the banking blocks 34, 4E! andAll in their guides and along the upwardly and rearwardly inclinedbearing surfaces against which they rest, with the result that thebanking surfaces of these blocks move rearwardly and upwardly from theirinactive positions shown in Fig. 1, and in a direction toward the frontof the mold opposite thereto. Such movement of the banking blocks willbe clear from Fig. 2 which shows the position of the block 34 prior tothe ascent of the transporter, and Fig. 3 which shows the position ofthis block at the completion of the ascent of the transporter, and fromFig. 4 wherein all three of the banking blocks 34, 40 and 4! are shownin the rearward position which they occupy at the completion of theascent of the transporter.

The second advance of the mold disk now takes place, with the bankingblocks 3-6, A and 4! in their rearwardly extended active positions shownin Fig. 4, in which positions these blocks limit such advance of themold disk by engagement of the mold I7 against the faces of these blocksbefore the mold it, then in the upper horizontal or casting position,can contact with the ribs !3 on the vise jaws, the relation of the mold8 with the rib-s 53 on the vise jaws at this time being indicated inFig. 7. The banking blocks thus serve to support the mold disk againstthe forward thrust of the slug ejecting device, and at the same timethey prevent conflict between the vise jaws and a mold standing in thecasting position. Subsequent to completion of the ejecting operation,the mold disk again retreats rearwardly, but meanwhile the transporter 4has descended from its uppermost or line removal level to its normalposition between the upper level and the casting level, so that the stud48 is no longer in engagement with the upper end of the slot ll.Consequently, upon retreat rearwardly of the mold disk, the bankingblocks 34, as and ii are free to slide downwardly by gravity theirguides, by a descent of the bars 27 and 39 which may then take placeand, due to the inclination of the surfaces on which these blocks slide,the blocks recede forwardly or in a direction away from the mold disk,so that when the latter advances for the next casting operation, itsadvancing stroke will not be limited by the banking blocks.

The usual knife wiper operating bar, together with the line transporteras commonly used on machines of this class, thus serves as motive powerfor moving the banking blocks into and out of active position tointerrupt the advance of the mold disk. These parts of the machinehowever, have been chosen for this purpose primarily because theirmovement is appropriate to effect the movements of the banking blocks atthe proper times in relation to the casting and ejecting operations, andit will be understood that while such means for moving the bankingblocks is generally preferable, other suitable means may be employed toaccomplish the objects of the present invention.

Although the invention has been shown and described in connection withcertain parts embodied in the usual form of slug casting machine of theclass referred to, it is to be understood that the invention is notrestricted thereto nor is it limited to the overcoming of the faultarising from the particular conditions hereinbefore set forth, since theinvention may be adapted to meet other conditions requiring correctionto remove similar faults in respect to establishing a proper relationbetween the mold at casting and ejecting positions and cooperative partsof the machine, or to the maintenance of such proper relation when itwould otherwise be disturbed during the advance and retraction of themold or mold disk in difierent operating positions.
